For most of the few million years that human life has existed on earth, we have managed to live with a balanced reliance on plants, trees and other natural biological resources of the planet. Mankind had been able to utilize the diversity of nature without threatening the continuance of any species. Within the last century, however, that balance has been disturbed. By our unrestricted use of the world's biological resources, we are causing a continual loss of living species. It is estimated that globally, the rate of extinction is one species per day. We are losing biodiversity.
The issue of human impact on biodiversity is not merely an academic environmental question. We rely on a rich source of natural biological products for a variety of aspects of our life. They provide food, medicines, cosmetics; they are used in areas such as soil productivity, waste degradation and pest control. The answer to the loss of biodiversity is not to stop using the products of nature. Instead, we need to use them in a sustainable way. There needs to be a greater recognition of the wealth – both ecologically and financially – that natural resources provide. Releasing that wealth will provide the encouragement to ensure sustainable uses of the resources.
